ANTICREEPER iEOR, RAILS.

Patented May 16, 1916.

Application filedOctober 9, 1915. Serial No. 54,984.

To all whom it may concern 7 Be it known that :1, WILLIAM D. .BnTLE a citizen of the United States, residing :at Woodbine, in thecounty. of Howard :and State of Maryland, have invented (3811131111 new and useful Improvements in Anticreepers for Rails, of which the following isa specification.

This invention relates to rail anchors de signed for preventing longitudinal :movement or creeping of railway. ra1ls, and its object is to provide a strong and reliablede vice of this kind which will firmly gr p the rail, and which is so secured that 1t is not liable to be shaken or jarred loose.

The invention also has :for its object to provide a rail anchor which can be easily applied, and which is simple 1n construction. a

With the herein stated objects in view, the invention consists in a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanyingdrawing, forming a part of this spec1ficat1on.

In the drawing, Figure 1 is a plan vlew showing the application of the inventlon; Fig. 2 is a side elevation thereof, and Fig. 3 is a cross-section on the line 33 of Fig. 1.

Referring specifically to the drawing, 5 denotes a railway rail, and 6 one of the tles on which said rail is supported. The rail has the usual base flanges 7.

The anchoring device which is the subv ject matter of the present application for patent comprises a base memberor plate 8 having at one end lateral extensions} terminating in jaws 10, and at the opposite end a means for positively gripping and clamping the rail. The jaws 10 are shaped to overhan and engage the respective base flanges F of the rail 5, and they are d1- agonally opposite each other. Whenthe base member, as a whole, is canted or given a slight twist or rotary movement in one direction, the jaws will be forced firmly against the base flanges. The gr1pp1ng means efiects this canting or twlst of the base member.

The gripping and clamping means referred to comprises a double wedglng cam clamping member consisting of a rotatable disk 11 which is adapted to have its edge wedged against the edge of one of the rail base flanges. The edge of the disk also has a shoulder 12 which overhangs the base flange and is inclined to form a cam. The disk is so positioned that its edgeengages the rail base edge, and the shoulder comes down on top thereof.

Thedisk 11 is pivoted eccentrically on a stud 13 rising from a lateral extension 1 at one end of the base member 8, said extension projecting outward from the rail base a sufficient distance so that the disk may engage the base flange as described.

'VVhen the disk 11 is turned to wedge against the edge of the rail base flange 7 the base member 8 is canted sufliciently to force theja-w-s 10 firmly against the respective base flanges, and at the same time the inclined shoulder 12 overhanging the base ,flange is wedged down on top thereof. The

device is thus firmly held in rail gripping position, and there is no danger of its being jarred or shaken loose.

The device will be so positioned beneath the rail 5 that the part 14 abuts against the tie 6, and as the device is clamped in fixed position of the rail, the tie serves as an abutment to hold the rail against a tendency to creep. On the bottom of the part 14 is a depending flange 15 adapted to be embedded in the ballast or road bed of the track. The flange extends transversely and thus assists to anchor the base plate 8.

A means is also provided for locking the disk 11 and preventing the same from turning in a direction to release the rail, said means comprising a pivoted pawl 16 carried by the edge of the disk, and engageable with ratchet teeth 17 on the top of the part 14. The disk also has a hand lever 18 for facilitating its operation, said lever being pivoted so that when it is not in use it may be swung down on top of the disk out of the way.

I claim:

1. A rail anchor comprising a base member having rail gripping means, and a cam clamp carried by said member and having wedging surfaces engageable respectively with the edge of a rail base flange and the top of said flange.

2. A rail anchor comprising a base member having rail gripping means and a tieabutting part, and a cam clamp carried by said member and having wedging surfaces engageable respectively with the edge of a rail base flange and the top of said flange.

3. A rail anchor comprising a base member having rail gripping means and a tieabutting part provided with a depending gr0und-penetrating flange, and a cam clamp carried by said member and having wedging surfaces engageable respectively with the edge of a rail base flange and the top of said flange.

4. A rail anchor comprising a base member having opposite rail gripping jaws, and a cam clamp carried by said member and having a wedging surface engageable with the edge of a base flange of the rail to cant the base member in a direction to engage the aws.

5. A rail anchor comprising a base member having opposite rail gripping jaws, and a cam clamp carried by sald member and having a wedging surface engageable with the edge of a base flange of the rail to cant the base member in a direction to engage the jaws, said clamp also having a wedging surface engageable with the top of said flange.

6. A rail anchor comprising a base member having opposite rail gripping jaws at one end, and a cam clamp carried by the other end of said member and having a wedging surface engageable with the edge of a base flange of the rail to cant the base member in a direction to engage the jaws.

7. A rail anchor comprising a base member having opposite rail gripping jaws, a cam clamp carried by said member and having a wedging surface engageable with the edge of a base flange of the rail to cant the base member in a direction to engage the jaws, and means for locking the clamp.

8. A rail anchor comprising a base member having opposite rail gripping jaws, and an eccentri'cally mounted rotatable disk carried by said member and adapted to wedge against the edge of a base flange of the rail, said disk also having a shoulder which overhangs the top of said flange and is inclined to Wedge thereagainst.

In testimony whereof I aflixvmy signature in presence of-two witnesses. 7
